From all posts here I take it that this is not possible so any suggestions on how to check the differences are welcome.

You can use any directory sync tool (FreeFileSync is popular for that around here; I use it myself) to sync a master library to a fully functional backup copy ('mirror' mode). However, if you have two libraries that are out of sync and you want to merge them, picking one as the master and copying the other into it (or copying both into a new library) from within Calibre is the only way.
EDIT: The
Find Duplicates plugin can search across libraries; that may help or even be what you need.
